2025 Season 3 Patch 2 Release Notes \[2025.06.21.01]

SIMULATION:

Connectivity

• [p]Fixed an issue where users could become invisible to others in the SIM after disconnecting and reconnecting.[/p]

Physics

• [p]Fixed an issue with how tires play with wet grass and gravel friction.[/p]
  • [p]This was also causing formula cars to snap and spin easily on wet gravel while at full-throttle.[/p]

Race Control

• [p]Fixed an issue where Race Restarts could get stuck on One-To-Green.[/p]

Graphics

• [p]Reduced the amount of visual popping that could be seen on many 3D curbs as a camera changed distances from them.[/p]
• [p]Many track grass textures have been updated to fix some splotchy patches and crab grass.[/p]

Controls

• [p]For force feedback, softened the profile of rumble strips in an effort to reduce the audible noise they produce in the 360Hz force feedback channel.[/p]
• [p]LFE system improvements for force feedback have been added, including:[/p]
  • [p]Moza wheels now have their master volume set -15 dB lower.[/p]
  • [p]Fanatec wheels now have their master volume set +5 dB higher.[/p]
  • [p]Road texture effect now has its default gain set to -30 dB.[/p]
  • [p]Drive shaft effect has been turned off and removed from the app.ini file.[/p]
  • [p]These changes should rebalance the mix for Moza wheel users, greatly reducing the audible noise the wheel produces when the Wheel LFE system is enabled. If you still find it is too loud, you can further reduce the volume in the Misc. tab of the Sim options, using the master volume slider in the Wheel LFE settings.[/p]

2025 Season 2 Patch 3 Release Notes [2024.04.02.02]

• This Patch Release contains updates and fixes for the 2025 Season 2 Release.
  
• This Patch Release also includes the new feature, Adaptive AI Racing for Single AI Sessions!
  

• Adaptive AI is now available for Single AI Sessions!
  
• - - Adaptive AI is an all new system that provides each iRacer an AI Racing experience that's tuned to their individual preferences and desired level of challenge. Rather than tuning difficulty percentages, with Adaptive AI users choose whether they are looking for a Low, Medium, or High level of challenge. This experience is dynamic and tuned to each iRacer, so one racer's Low might be another racer's Medium. While Adaptive AI is built for iRacers of all abilities, it does have a sweet spot and it's possible that some of our fastest racers might exceed the pace that the system can provide. As with all iRacing systems, Adaptive AI will continue to evolve and improve as we collect and incorporate iRacer feedback.
  
• - - Adaptive AI will make its debut in Single Race, with a follow-up planned for Hosted iRacing and AI Seasons at a later date.
  
• AI Drivers have improved their racing lines at USA International Speedway.
  
• AI Drivers have improved their racing skills with the NASCAR Truck Series Class Trucks.
  

• The physics processing for collisions involving opponent vehicles has been updated for improved accuracy.
  
• - - Opponent cars now automatically update their physics processing frequency to a much higher rate any time they detect they are in close proximity to any object, or whenever a collision occurs.
  
• - - - - This alleviates an issue where opponent vehicles could sometimes appear to snag on walls, climb up objects, or trigger other visual oddities.
  
• - - Torque scaling applied during impacts to wheels has also been adjusted. Opponent vehicles now behave much more realistically when striking walls with their wheels.
  

• Updated the appearance of dynamic track debris within the space tangential to the track surface.
  
• Fixed an issue with normal mapping of track debris, making their visible bumpiness more correct.

• Some Foreign Language Spotter Packs have been updated.
  

• Fixed an issue where the training Race Line was always white, instead of color-coded to indicate braking and acceleration zones.
  

• For custom paints, a headlight has been moved to the decal layer, so custom paints may once again stamp numbers over them.
  
• For the damage model, friction parameters have been increased on the tire and rim sidewalls to prevent any benefits from wall-riding.
  

• Fixed an error where the left-front tire change always required an additional 5 seconds. This tire changer has been re-assigned to a new job more befitting his talents.
  

• Fixed an issue where the shadow of this car was incorrect.
